Procedure

Diacid 62 (150 mg, 0.609 mmol), 8-aminoquinoline (211 mg, 1.462 mmol), and DMAP (5 mg) were dissolved in THF (6 mL). To this solution was added EDC (350 mg, 1.827 mmol) and the reaction allowed to proceed overnight. The mixture was concentrated under reduced pressure and the product purified by flash chromatography (40% EtOAc/hexanes). Evaporation of the combined product fractions left 63 as a light brown solid (100 mg, 0.201 mmol, 14%). 1H-NMR (400 MHz, DMSO-d6) δ 10.85 (s, 2H), 8.92 (dd, 2H), 8.64 (dd, 2H), 8.40 (dd, 2H), 7.68 (dd, 2H), 7.62 (dd, 2H), 7.57 (t, 2H), 4.35 (t, 1H), 3.98 (q, 2H), 2.24 (t, 2H), 2.00 (m, 2H), 1.51 (m, 2H), 1.37 (m, 4H), 1.12 (t, 3H).
